9 Claims.

My invention relates to boxes and has for an object to provide a box comprising a body having inner and outer walls secured together away from the edges thereof to leave the marginal portions of said walls unattached.

Another object of the invention resides in providing a closure for the box having flanges formed along the edges thereof and adapted to be inserted between free marginal portions of the walls of the body of the box.

A still further object of the invention resides in constructing the inner andouter walls of the body of the box substantially coextensive in height.

An object of the invention resides in attaching said inner and outer walls together along a belt intermediate the upper and lower portions thereof.

A still further object of the invention resides in securing said inner and outer walls together through gluing.

Another object of the invention resides in constructing the inner and outer walls from two sheets of stock with the grain running in opposite directions and in, securing said stock together while planiform.

A feature of the invention resides in scoring the sheets of stock after the same have been secured together and along pairs of spaced parallel lines and in thereafter folding the stock along said lines to cause the inner sheet tobuckle at the corners and separate from the outer sheet at the unattached portions thereof.

Another object of the invention resides in constructing the box open at the top and bottom and in further constructing the box with spaced parallel walls at both the top and bottom.

A still further object of the invention resides in providing a box with upper and lower closures, each having a cover and flanges formed along the edges thereof for insertion between walls of the box.

An object of the invention resides in constructing one of the sides of the box of the single sheet of stock and the other three sides of double sheets 5 of stock and in providing a closure for the box hinged to the side constructed from the single sheet of stock.

Other objects of the invention reside in the details of construction thereof and in the novel combination and arrangement of parts hereinafter illustrated and/or described.

In the shipping of the various articles in paper boxes, the customary practice has been to discard the box after the same has been once used. Where commodities are being shipped repeatedly from the same place to the same destinations, boxes may be advantageously used over again. In such cases, rigid and substantial boxes may be employed which will stand considerably more abuse than the ordinary paper boxes and which when used over again greatly reduce the packing cost. In the shipment of various commodities, it frequently occurs that the closures therefore become damaged by resting upon moist surfaces or otherwise. The present invention provides a box which will withstand repeated use, which is extremely sturdy and substantial in construction and with which replaceable closures of inexpensive construction may be utilized.

The form of my invention shown in Fig. 1 comprises a body 10, open at the upper and lower portions thereof and adapted to be closed by means of upper and lower closures 11 and 12. The body 10 comprises sides 15 and 16- and ends 17 and 18, which may be collapsed into a planiform state for shipment when desired. The body 10 is constructed with an inner wall 32 and an outer wall 33 which give added strength to the box and also provide for the attachment of the closure to the box. These parts will now be described in detail.

The body 10 is constructed of two elongated sheets of paper board, or similar material indicated at 13 and 14. These sheets are of the same length and form the various sides and ends of the box. The sheet 14 is of a width equal to the height of the box, while the sheet 13 is somewhat. narrower. The grain in sheet 14 runs vertical, while the grain in sheet 15 runs horizontal for a purpose to be later brought out.

In constructing the blank from which the body 10 is formed the two sheets, 13 and 14 are glued together along a longitudinal band defined by the dotted lines 19, 20 and 21 in Fig. 4, leaving the marginal portions of said sheets indicated at 22 and 23 unattached. In the gluing of these sheets the sheet 13 is equally spaced from the edges of the sheet 14 to cause said latter sheet to project outwardly beyond the edges of sheet 13, so as to 12 form protruding portions or tabs 24 and 25 about the perimeter of the body. After the blank 10 has been glued, said blank' is scored transversely along pairs of parallel lines 26 and 27, which pairs are spaced from one another distances corresponding with the length and breadth of the box. These pairs of score lines divide the box into the ends 17 and 18 and into the sides 16 and 15 and leave a flap 28 at the end of the side 15. 4

In assembling the body of the box, the blank 10 is folded along the various score marks 2627 to form corners for the box as shown in Fig. 2. Upon the folding of the composite structure forming the body of the box, the glued or attached portions thereof fold jointly in the ordinary manner. However, the unattached portions indicated at 2223 fold as shown in Fig. 5, the outer wall or sheet 13 taking a smooth bend while the inner sheet or wall 14, buckles as designated at 29. This has the effect of causing the unattached part 23 of the inner wall to separate from the outer wall 13 and to leave spaces 30 between said walls and outwardly of the glued part of the body, which is facilitated by the running of the grain of the inner wall in the direction of the fold. After the body structure has been properly folded, the flap 28 on end 15 is inserted between the ends of the walls 13 and 14, which, due to the termination of the glue at the line 21, are separable to receive said flap. The entire structure then may be secured together by gluing or by means of staples indicated at 31, in Figs. 1 and 2.

The closures 11 and 12 are identical in construction and only closure 12 has been separately illustrated and will be described in detail. This closure is constructed from a sheet of material and is scored and folded in a suitable manner to form the structure shown in Fig. 3. This closure comprises a cover 34, formed along the edges thereof, with outwardly bent flanges 35. These flanges are preferably beveled along the edges 36 thereof, and are adapted to be inserted into the spaces 30, formed between the walls 13 and 14 and above the portions 22 and 23 of the body of the box.

In storing or shipping the boxes, the body 10 is collapsed and brought into a planiform state. The flanges 35 of the closures 11 and '12, are similarly bent out into a planiform state, permitting of tying the parts in compact bundles or bales. When a box is to be used, the body is folded into rectangular form and the flanges of the closures folded at right angles to the cover portions thereof. The flanges 35, of the closures may then be readily inserted into the spaces 30, between the portions 22 and 23 of the box, which serve to hold the said closures attached to the body of the box. In applying the flanges withinthe spaces 30, the said flanges are caused to abutagainst the protruding portions or tabs 24 and 25 of the box which served to guide the flanges into said spaces. These tabs hence facilitate the application of the closures to the box and at the same time maintain the edges of the outer wall 33 of the box away from the top and bottom thereof, so as to protect the same and prevent injury thereto. After the box has been erected and the closures applied, the entire box may be bound through'cord, metallic bands or adhesive tape, in the customary manner, which prevents accidental displacement of the closures.

In Figs. 6 and '7, I have shown a modification Y of the invention which differs slightly from that shown in Figs. 1' and 2. In this box only one end and'two sides of the box'are formed with double walls. The closures in this de'viceare hinged to the other end of the box and are permanently attached to the box.

The body of the box indicated at 43, similar to that shown in Figs. 1 and 2, comprises sides 37 and 38, and ends 39 and 40. The body of the box is open at the upper and lower portions thereof and is closed by two closures 41 and 42, which are hingedly connected to the end 40.

The body of the box is constructed from two sheets of material 44 and 45 of similar dimen-. sions to the sheets 13 and 14 of the body number 10, with the exception that these sheets are of a length sufficient to form three only of the sides of the box. These sheets are glued together along acentral band defined between the lines 46 and 47 and 66 and 6'7, to leave marginal unattached portions, 68, 69, '70, and 71, and is scored transversely along parallel lines 48 and 49 to form the two sides, 38 and 37 and the end 39.

The two closures 41 and 42 and the end 40 of the box, are formed from another blank 50, shown in Fig. 8. This blank is constructed of a single sheet of material, which is scored along four transverse lines, 51, 52, 53 and 54, and along two longitudinal lines, 55 and 56. The score lines 51, 54, 55 and 56 are closeto the edges of the sheet to form narrow marginal portions. The sheet is out along these marginal portions and at the various intersections of the various score lines as indicated at 57, to provide a number of flanges 58, 59, 60, 61, 62, 63, 64 and 65, which extend outwardly from the closures 41 and 42 and the end 40 of the box proper.

In constructing the box, the two intermediate flanges, 61 and 65 are inserted between the unattached end portions, 69 and. 71 of the two sheets, 44 and 45, after the same have been properly folded at the corners, and are secured to the body 43 through staples 168, or other similar means. The flanges 58, 59 and 60, on the closure 41, may be inserted in the spaces 169, between the unattached portions 68, of the body, while the flanges 62, 63 and 64, on the closure 42 may be inserted in the corresponding spaces between the unattached portion '70 of said body. The sheet 44 is preferably constructed of a height slightly greater-than that of the sheet 45, to assist in the insertion of the flanges in these spaces. When the closures have been properly applied to the box, the ends of the sheet 44 are completely covered as in the other form of the invention. However with this form, the closures may not be replaced when the closures originally attached to the box become injured or damaged.

On the other hand, the closures are more easily applied to the box and cannot be lost.

My invention is highly advantageous in that an extremely rugged and substantial box may be constructed at a cost not greatly exceeding that of the ordinary box. The body of the box may be readily collapsed for storage, or shipment and occupies a minimum of space. Due to the manner of constructing the body of the box, the said body will support an appreciable weight, so that a number of boxes constructed in accordance with my invention may be safely piled one upon the other. The closures for the box are rather inexpensive and may be replaced whenever the same wear out or become damaged. These closures also protect the body of the box, so that the body, which is the more expensive part of the box may be used repeatedly. The closures are readily applied to the body of the box and the flanges formed therein are readily inserted into the proper spaces through the tabs formed on the innerwalls'of the body.

Changes in the specific form of my invention as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention.

Having described my invention, what I claim as new and desire to protect by Letters Patent is:

1. A box including a body open at the upper portion thereof and comprising ends and sides, one thereof having an inner and an outer wall, secured together along a line disposed below the upper edges of said walls to leave the upper marginal portions thereof unattached, the inner wall of said box being higher than the outer wall, the outer walls of the adjoining ends and sides of said box being secured together at the corners throughout the extent thereof, and the cover having a flange formed along one of the edges thereof and insertable between the free marginal portions of said walls, said flange being adapted to be guided into the space between said walls through the extending portion of the inner wall.

2. A box including a body open at the upper and lower portions thereof and comprising sides and ends one thereof having inner and outer walls, the height of the inner wall being greater than that of the outer wall, said inner wall extending beyond said outer wall at both the top and bottom, said walls being secured together along a belt intermediate the upper and lower edges of said walls to leave the upper and lower marginal portions thereof unattached, the outer walls of the adjoining ends and sides of said box being secured together at the corners throughout the extent thereof, closures for the box comprising covers having flanges formed along the edges thereof corresponding to the double walls of the box and adapted to be inserted between the unattached portions of the double walls and to be guided into position therebetween through the protruding portions of said inner walls.
